Numenius is a geographer by training and temperament. He is a Bay Area native, and grew up roaming the East Bay hills. Pica takes her cue from Pica nuttalli, the endemic magpie of central California, chatty and alighting on gleaming things. Pica has another blog, Bird by Bird, in which she records a sketch of a bird per day.

That is a great article! Thanks for sharing it.
